Abstract

Present study deals with the vegetation type mapping, structure and composition analysis of the tropical forests, spread over 1,294 km2 area in South Andaman Islands. Seventeen vegetation classes spreading over 89.92% forested area of the islands were mapped with the overall accuracy of 88.89%. Evergreen, semi-evergreen and mangrove forests were reasonably well distributed forests, while moist deciduous and littoral evergreen were narrowly restricted. The stocking was quite variable across the forest types. 60.04% of forested area was under medium to high canopy density. Secondary and degraded forest types were mapped. Information on floristic composition, structure and diversity of various forest types were obtained from 84 field sample plots. An inventory of 423 species of plants from 101 families included 155 trees, 84 shrubs, 150 herbs and 84 climbers. Tree density and mean basal area ranged from 517 to 900 stems ha−1 and 36.15 to 53.58 m2 ha−1 respectively. Evergreen forests accounted for highest diversity followed almost equally by semi-evergreen and moist deciduous forests.
